Less barium enema, more colonoscopy: A 12-year nationwide population-based study in Taiwan.

BACKGROUND: Colorectal cancer (CRC) is the second most common and third most fatal cancer in Taiwan. To reduce incidence and mortality rates from cancer, including CRC, the Health Promotion Administration in Taiwan initiated the National Program on Cancer Prevention in 2005. For patients who have a positive fecal occult blood test, colonoscopy is recommended, and double-contrast barium enema (BE) is reserved as an alternative for those who cannot receive colonoscopy. In addition, single-contrast BE is sometimes used in pediatrics to evaluate colonic condition. This study evaluated the usage trends of BE and colonoscopy in Taiwan. METHODS: Data from the National Health Insurance Research Database from 2001 to 2013 were used in this study. Patients who received BE and colonoscopy were identified using the procedure codes of the National Health Insurance program. Age-standardized, yearly rates of BE and colonoscopy procedures were calculated. RESULTS: According to the data, the total number of colonoscopies increased 3.7-fold from 2001 to 2013. The compound annual growth rates for BE and colonoscopy were -5.36% and 10.47%, respectively, during the same period. The compound annual growth rates for BE and colonoscopy were -3.89% and 11.64% from 2005 to 2009, and -11.36% and 9.82% from 2010 to 2013, respectively. BE was conducted significantly more frequently than colonoscopy in patients who were aged <12 years and in female patients. CONCLUSION: Professional association guidelines, national cancer prevention programs, patient and physician preferences, and increasing awareness and knowledge of CRC may all contribute to the increasing use of colonoscopy and the dramatic decline in the use of BE in Taiwan.

Clinical Value of Contrast Enema Prior to Ileostomy Closure.

Purpose To determine the value of routine contrast enema of loop ileostomy before elective ileostomy closure regarding the influence on the clinical decision-making. Materials and Methods Retrospective analysis of contrast enemas at a tertiary care center between 2005 und 2011. Patients were divided into two groups: Group I with ileostomy reversal, group II without ileostomy closure. Patient-related parameters (underlying disease, operation method) and parameters based on the findings (stenosis, leakage of anastomosis, incontinence) were evaluated. Results Analyzing a total of 252 patients in 89 % (group I, n = 225) ileostomy closure was performed. In 15 % the radiologic report was the only diagnostic modality needed for therapy decision; in 36 % the contrast enema and one or more other diagnostic methods were decisive. In 36 % the radiological report of the contrast imaging was not relevant for decision at all. In 11 % (group II, n = 27) no ileostomy closure was performed. In this group in 11 % the radiological report of the contrast enema was the only decision factor for not performing the ileostomy reversal. In 26 % one or more examination was necessary. In 26 % the result of the contrast examination was not relevant. Conclusion The radiologic contrast imaging of loop ileostomy solely plays a minor role in complex surgical decision-making before planned reversal, but is important as first imaging method in detecting complications and often leads to additional examinations. Key points · Contrast enema of loop ileostomy before planned ileostomy closure is a frequently performed examination.. · There exist no general guidelines that give further recommendations on decision-making planning ileostomy closure.. · The radiologic contrast imaging of loop ileostomy solely plays a minor role in decision-making before planned reversal, but is important as first imaging method..

Routine contrast enema is not required for all infants prior to ostomy reversal: A 10-year single-center experience.

INTRODUCTION: The incidence of intestinal stricture is low for most conditions requiring a primary small bowel stoma in infants. Routine performance of contrast enemas (CE) prior to stoma closure adds cost and radiation exposure. We hypothesized that routine CE prior to ostomy reversal is not necessary in all infants, and sought to identify a subset of patients who may benefit from preoperative CE. METHODS: Medical records of infants under age 1 (N=161) undergoing small bowel stoma reversal at a single institution between 2003 and 2013 were retrospectively reviewed. Student's T-test was used to compare groups. RESULTS: Contrast enemas were performed on 80% of all infants undergoing small bowel ostomy reversal during the study period. Infants with necrotizing enterocolitis (NEC) were more likely to have a CE than those with intestinal atresia (p=0.03) or those with all other diagnoses combined (p=0.03). Nine strictures were identified on CE. Of those, 8 (89%) were in patients with NEC, and only 4 were clinically significant and required operative resection. The overall relevant stricture rate was 2.5%. No patient that underwent ostomy takedown without CE had a stricture diagnosed intraoperatively or an unrecognized stricture that presented clinically after stoma takedown. CONCLUSIONS: Routine CE is not required prior to small bowel ostomy reversal in infants. We recommend judicious use of enema studies in patients with NEC and high likelihood of stricture.
